However as Keith says, you can absolutely get the car tuned for that exhaust (within the limit of the factory injectors). What is happening now is that you have made it easier for the turbo to make boost pressure by improving the exhaust flow. The car is sensing that boost is higher than it expects and so is cutting the boost, hence the power drop. The tune will allow the car to make a bit more boost, plus revise the overboost cut settings. If you pay the little bit extra now for injectors, you will get a much better result from the money you are spending on the tune. If you do the injectors later you will need to pay for a tune again. You can upgrade the intercooler later without needing another tune. The wastegate flapper and port seems to be needed in some cases and not others. Mine is fine with a 4" dump and cat, but I still have the factory cat back. Might pay to have a chat to a few workshops too and have a read on here about who is recommended. Pitlane seems to be the go for most Vic people on here. Edit: was typing while Keith was typing. That's actually exactly what I did - my car was making 300kw on stock injectors when I got it, and I replaced them with F6 injectors. Thank you all for all the great information. Lastly, I just want to know how long I can drive my car the way it is right now without getting all the required things done? Link to comment Share on other sites More sharing options...

FT096 New Member 9 Member For: 3y 10m 19d Posted 01/06/20 02:11 PM Author Share Posted 01/06/20 02:11 PM So I went in today to get a quote from a highly recommended tuner, he split the quote into 2, required work and optional extras. Below is the quote and what they’re telling me to do and all it’s costs, what are your thoughts? Link to comment Share on other sites More sharing options...

The rest is fine/normal-ish. Link to comment Share on other sites More sharing options...

El Andrew Gold Donating Members 2,019 Member For: 8y 11m 28d Gender: Male Location: Canberra ACT Posted 01/06/20 08:27 PM Share Posted 01/06/20 08:27 PM Hey mate. I would suggest for 300 odd kW you ignore head studs, valve springs and compressor wheel - absolutely unnecessary unless the car has issues with anybody those items or you are aiming for much more than 300-320.Injectors, yes. Fuel pump, optional as the factory pump will just get you there. But good insurance bro know the fuel system can keep up and it's cheap. You can do it separately or later without affecting the tune.Flapper mod - maybe, maybe not. Sounds like you are being quoted for an actuator upgrade too which is not needed. Anyone know how much a flapper mod should cost? As Keith says, a lot of the labour is in removing and replacing the turbo, then porting the wastegate. The flapper itself is about $20.
